Answer:
x = 60
Step-by-step explanation:
The two angles shown here are known as corresponding angles. This means they both equal the same amount of degrees. Knowing this, we can set up an equation:
2x + 15 = 135
2x = 120
x = 60
Therefore, x = 60
You can check your answer by substituting the answer for x:
2(60) + 15 = 135
120 + 15 = 135
135 = 135

I can give you alittle head start. I hope it kinda helps.
Step-by-step explanation:
Dentist A: 50 + 20x
Dentist B: 70 + 5x

Answer:
7. 250%
8. 400%
9. 667%
10. 769%
11. 263%
12. 125%
13. 137%
14. 526%
Step-by-step explanation:
divide the first number by the second number, then multiply that answer by 100
so kind of like: Number1 ÷ Number2 = x
then you do x × 100
and that's your answer

Answer:
No
Step-by-step explanation:
4/20 is a fraction just like 5/20. 5 is higher than 4, which means it'd take less time to get to 20 using five than it would with 4
You did not include the given line to which your line is parallel to.
Nevertheless, I can explain you how to solve this problem and which the possible solutions are.
1) x-intercept = - 3 = y = 0
The only two equations that include the point (-3,0) are y = x + 3 and y = - x - 3 (you likely forgot to place the negative signs).
You can prove that in this way:
a) y = x + 3
y = 0 => x + 3 = 0 => x = - 3
b) y = - x - 3
y = 0 => - x - 3 = 0 => x = - 3
Then, so far you have two options: y = x + 3 and y = - x - 3.
2) The slope of y = x + 3 is 1 and the slope of y = - x - 3 = - 1 (the coefficient of the x).
3) You know that line whose equation you are determining is parallel to the given line. That means that their slope are the same. So, your next step is to determine the slope of the given line. It shall be either 1 or - 1. Once you have the slope, you will know whether the solution is y = x + 3 or y = - x - 3.
